Question

How does energy flow
in living beinge?​

Answer 1

• The sun is the ultimate source of energy.

• Plants use the energy from the sun to produce food.

• The food chain always starts with the producers. Because the energy produced by them further passes down to various trophic levels.

• Plants capture 2-10 percent of the photosynthetically active radiation and this small amount of energy sustains the entire living world.

• All the animals are dependent on plants to fulfill their food need.

      Therefore animals are called consumers.

• If animals feed on plants then they are said to be primary consumers, the animal which feeds on primary consumers are said to be secondary consumers.
• Only 10% of the energy is transferred to each trophic level from the preceding trophic level.

Answer 2

Answer:

1. The energy flow through living organisms starts with sunlight and photosynthesis, then travels through the food chain in bite-sized chunks.

2. Primary producers, primary consumers, secondary consumers, and decomposers are all part of the food chain.

3. The path is linear as the energy present in one step is transferred to the next.

4. You can find specific examples of this pathway in an ecosystem.
